Enable branch protection rules in Github at the Organisation level

Question

Is it possible to enable branch protection rules at the organisation level in Github so that all repositories part of that organisation inherit these rules for the applied branches. Right now its really a hassle to enable those same set of rules on a per repo basis for same set of branches.

Answer 1

I got it to work using a simple ruby script that makes use of the GitHub APIs :-

require "json"
require "logger"

LOGGER = Logger.new(STDOUT)

def run(cmd)
  LOGGER.debug("Running: #{cmd}")
  output = `#{cmd}`
  raise "Error: #{$?}" unless $?.success?
  output
end


def repos(page = 1, list = [])
  cmd = %Q{curl -s --user "user:pwd" https://github_url/api/v3/orgs/org_name/repos?page=#{page}}
  data = JSON.parse(run(cmd))
  list.concat(data)
  repos(page + 1, list) unless data.empty?
  list
end

repos.each do |repo|
  require 'net/http'
require 'uri'
require 'json'

uri = URI.parse("https://github_url/api/v3/repos/org_name/#{repo["name"]}/branches/master/protection")
request = Net::HTTP::Put.new(uri)
request.basic_auth("user", "pwd")
request["Accept"] = "application/vnd.github.luke-cage-preview+jso"
request.body = JSON.dump({
  "required_status_checks" => {
    "strict" => true,
    "contexts" => [
      "continuous-integration/travis-ci"
    ]
  },
  "enforce_admins" => true,
  "required_pull_request_reviews" => {
    "dismiss_stale_reviews" => true
  },
  "restrictions" => nil
})

req_options = {
  use_ssl: uri.scheme == "https",
}

response = Net::HTTP.start(uri.hostname, uri.port, req_options) do |http|
  http.request(request)
end
end

Taken from @Ashley 's answers, updated it a bit, with a slight change to reflect current Github's API URLs and, added customization using GITHUB_ORG and GITHUB_ACCESS_TOKEN environment variables.

require "json"
require "logger"

$org = ENV["GITHUB_ORG"]
$token = ENV["GITHUB_ACCESS_TOKEN"]

LOGGER = Logger.new(STDOUT)

def run(cmd)
  LOGGER.debug("Running: #{cmd}")
  output = `#{cmd}`
  raise "Error: #{$?}" unless $?.success?
  output
end


def repos(page = 1, list = [])
  cmd = %Q{curl -s -u dummy:#{$token} https://api.github.com/orgs/#{$org}/repos?page=#{page}}
  data = JSON.parse(run(cmd))
  list.concat(data)
  repos(page + 1, list) unless data.empty?
  list
end

repos.each do |repo|
p(repo["name"])
  require 'net/http'
require 'uri'
require 'json'

uri = URI.parse("https://api.github.com/repos/#{$org}/#{repo["name"]}/branches/master/protection")
request = Net::HTTP::Put.new(uri)
request.basic_auth("dummy", $token)
request["Accept"] = "application/vnd.github.luke-cage-preview+jso"
request.body = JSON.dump({
  "required_status_checks" => {
    "strict" => true,
    "contexts" => []
  },
  "enforce_admins" => true,
  "required_pull_request_reviews" => {
    "dismiss_stale_reviews" => true
  },
  "restrictions" => nil
})

req_options = {
  use_ssl: uri.scheme == "https",
}

response = Net::HTTP.start(uri.hostname, uri.port, req_options) do |http|
  http.request(request)
end
p(response)
end

You should try using the Github API's update branch protection endpoint with some kind of automated process to apply branch protection rules to all new branches in your organization.

PUT /repos/:owner/:repo/branches/:branch/protection
